* cluster/ec: Fix lk-owner set race in ec_unlockPranith Kumar K2017-01-171-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Rename does two locks. There is a case where when it tries to unlock it sends xattrop of the directory with new version, callback of these two xattrops can be picked up by two separate epoll threads. Both of them will try to set the lk-owner for unlock in parallel on the same frame so one of these unlocks will fail because the lk-owner doesn't match. Fix: Specify the lk-owner which will be set on inodelk frame which will not be over written by any other thread/operation. >BUG: 1402710 >Change-Id: I666ffc931440dc5253d72df666efe0ef1d73f99a >Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> >Reviewed-on: http://review.gluster.org/16074 >Reviewed-by: Xavier Hernandez <xhernandez@datalab.es> >Smoke: Gluster Build System <jenkins@build.gluster.org> >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >CentOS-regression: Gluster Build System <jenkins@build.gluster.org> BUG: 1412922 Change-Id: I18c553adaa0cbc8df55876accc1e1dcd4ee9c116 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/16394 Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Xavier Hernandez <xhernandez@datalab.es> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org>

* posix: make sure atime and mtime are set when calling lutimes()Niels de Vos2017-01-081-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When overwriting an existing file with O_TRUNC, the 'atime' was set to 0, meaning the Epoch (01-Jan-1970 UTC).

* syncop: fix conditional wait bug in parallel dir scanRavishankar N2016-12-111-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The issue as seen by the user is detailed in the BZ but what is happening is if the no. of items in the wait queue == max-qlen, syncop_mt_dir_scan() does a pthread_cond_wait until the launched synctask workers dequeue the queue. But if for some reason the worker fails, the queue is never emptied due to which further invocations of syncop_mt_dir_scan() are blocked forever. Fix: Made some changes to _dir_scan_job_fn - If a worker encounters error while processing an entry, notify the readdir loop in syncop_mt_dir_scan() of the error but continue to process other entries in the queue, decrementing the qlen as and when we dequeue elements, and ending only when the queue is empty. - If the readdir loop in syncop_mt_dir_scan() gets an error form the worker, stop the readdir+queueing of further entries. > Reviewed-on: http://review.gluster.org/16073 > Smoke: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> (cherry picked from commit 2d012c4558046afd6adb3992ff88f937c5f835e4) Change-Id: I39ce073e01a68c7ff18a0e9227389245a6f75b88 BUG: 1403192 Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reviewed-on: http://review.gluster.org/16096 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>
* libglusterfs: Fix a read hangPoornima G2016-11-281-3/+5

RCA: ==== In certain cases, ioc_readv() issues STACK_WIND_TAIL() instead of STACK_WIND(). One such case is when inode_ctx for that file is not present (can happen if readdirp was called, and populates md-cache and serves all the lookups from cache). Consider the following graph: ... io-cache (parent) | readdir-ahead | read-ahead ... Below is the code snippet of ioc_readv calling STACK_WIND_TAIL: ioc_readv() { ... if (!inode_ctx) STACK_WIND_TAIL (frame, FIRST_CHILD (frame->this), FIRST_CHILD (frame->this)->fops->readv, fd, size, offset, flags, xdata); /* Ideally, this stack_wind should wind to readdir-ahead:readv() but it winds to read-ahead:readv(). See below for explaination. */ ... } STACK_WIND_TAIL (frame, obj, fn, ...) { frame->this = obj; /* for the above mentioned graph, frame->this will be readdir-ahead * frame->this = FIRST_CHILD (frame->this) i.e. readdir-ahead, which * is as expected */ ... THIS = obj; /* THIS will be read-ahead instead of readdir-ahead!, as obj expands * to "FIRST_CHILD (frame->this)" and frame->this was pointing * to readdir-ahead in the previous statement. */ ... fn (frame, obj, params); /* fn will call read-ahead:readv() instead of readdir-ahead:readv()! * as fn expands to "FIRST_CHILD (frame->this)->fops->readv" and * frame->this was pointing ro readdir-ahead in the first statement */ ... } Thus, the readdir-ahead's readv() implementation will be skipped, and ra_readv() will be called with frame->this = "readdir-ahead" and this = "read-ahead". This can lead to corruption / hang / other problems. But in this perticular case, when 'frame->this' and 'this' passed to ra_readv() doesn't match, it causes ra_readv() to call ra_readv() again!. Thus the logic of read-ahead readv() falls apart and leads to hang. Solution: ========= Modify STACK_WIND_TAIL() as: STACK_WIND_TAIL (frame, obj, fn, ...) { next_xl = obj /* resolve obj as the variables passed in obj macro can be overwritten in the further instrucions */ next_xl_fn = fn /* resolve fn and store in a tmp variable, before modifying any variables */ frame->this = next_xl; ... THIS = next_xl; ... next_xl_fn (frame, next_xl, params); ... } BUG: 1399018 Change-Id: Ie662ac8f18fa16909376f1e59387bc5b886bd0f9 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: http://review.gluster.org/15934 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>

* libglusterfs: add gf_get_mem_type()Niels de Vos2016-10-182-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gfapi needs to provide a function towards applications to free memory that it allocated. Depending on how the application is compiled/linked, it could use a different memory allocator than Gluster itself. Therefore it is not safe for gfapi to request applications to free memory with 'standard' free(). Examples for this are Gluster allocated structures with GF_CALLOC() when memory accounting is enabled (the default). Some gfapi functions use malloc() to allocate memory as a workaround, but the free() from the jemalloc implementation should not be combined with the malloc() from glibc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Milind Changire reported that GlusterFS fails to build on RHEL5 because linux/oom.h is unavailable. Milind's initial patch disables OOM adjustment completely for those environments that do not have this header. However, I'd take another approach that: 1) checks for linux/oom.h in compile-time and defines necessary constants if the header is not present; 2) checks for available OOM API in /proc in run-time and uses it accordingly. This allows OOM to be adjusted properly on RHEL5 (the kernel is pretty new to present /proc API for that) as well as RHEL6 (the kernel has many thing backported including new /proc API). > Reviewed-on: http://review.gluster.org/15587 > Smoke: Gluster Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > Reviewed-by: Niels de Vos <ndevos@redhat.com> > Tested-by: Oleksandr Natalenko <oleksandr@natalenko.name> Change-Id: I1bc610586872d208430575c149a7d0c54bd82370 BUG: 1383694 Signed-off-by: Oleksandr Natalenko <onatalen@redhat.com> Reviewed-on: http://review.gluster.org/15623 Tested-by: Oleksandr Natalenko <oleksandr@natalenko.name> Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Niels de Vos <ndevos@redhat.com>

* cluster/afr: Prevent split-brain when bricks are brought off and on in ↵Krutika Dhananjay2016-08-222-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cyclic order Backport of: http://review.gluster.org/15080 When the bricks are brought offline and then online in cyclic order while writes are in progress on a file, thanks to inode refresh in write txns, AFR will mostly fail the write attempt when the only good copy is offline. However, there is still a remote possibility that the file will run into split-brain if the brick that has the lone good copy goes offline *after* the inode refresh but *before* the write txn completes (I call it in-flight split-brain in the patch for ease of reference), requiring intervention from admin to resolve the split-brain before the IO can resume normally on the file. To get around this, the patch does the following things: i) retains the dirty xattrs on the file ii) avoids marking the last of the good copies as bad (or accused) in case it is the one to go down during the course of a write. iii) fails that particular write with the appropriate errno. This way, we still have one good copy left despite the split-brain situation which when it is back online, will be chosen as source to do the heal. > Change-Id: I9ca634b026ac830b172bac076437cc3bf1ae7d8a > BUG: 1363721 > Signed-off-by: Krutika Dhananjay <kdhananj@redhat.com> > Reviewed-on: http://review.gluster.org/15080 > Tested-by: Pranith Kumar Karampuri <pkarampu@redhat.com> > Smoke: Gluster Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Ravishankar N <ravishankar@redhat.com> > Reviewed-by: Oleksandr Natalenko <oleksandr@natalenko.name> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> (cherry picked from commit fcb5b70b1099d0379b40c81f35750df8bb9545a5) Change-Id: I157f1025aebd6624fa3d412abc69a4ae6f2fe9e0 BUG: 1367272 Signed-off-by: Krutika Dhananjay <kdhananj@redhat.com> Signed-off-by: Oleksandr Natalenko <oleksandr@natalenko.name> Reviewed-on: http://review.gluster.org/15221 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>

This results in an extra memcpy() which can be avoided if we could implement an api that would return an iobuf whose ptr is page-aligned. That way the iobuf->ptr can be directly passed to sys_pread() as a parameter by posix translator.

We'll always keep one reference to an open file on the same inode. It's irrelevant if the reference is new or old.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lk_flags from posix_lock_t structure is the primary key used to differentiate locks as either advisory and mandatory type. During lock migration this field is not read in getactivelk() call path. So in order to copy the exact lock state from source to destination it is necessary to include lk_flags within lock_migration_info_t structure to maintain accurate state. This change also includes minor modifications to setactivelk() call to consider lk_flags during lock migration. > Reviewed-on: http://review.gluster.org/14189 > Smoke: Gluster Build System <jenkins@build.gluster.com> > Reviewed-by: Susant Palai <spalai@redhat.com> > Reviewed-by: Poornima G <pgurusid@redhat.com> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.com> > Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> (cherry picked from commit deaf8439fc42435988aae6a7b9ab681cc0d36b09) Change-Id: I20a7b6b6a0f3bdac5734cce8a2cd2349eceff195 BUG: 1337805 Signed-off-by: Anoop C S <anoopcs@redhat.com> Reviewed-on: http://review.gluster.org/14457 Smoke: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>

* cluster/afr: Don't let NFS cache stat after writesPranith Kumar K2016-05-142-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Afr does post-ops after write but the stat buffer it unwinds is at the time of write, so if nfs client caches this, it will see different ctime when it does stat on it after post-op is done. From NFS client's perspective it thinks the file is changed. Tar which depends on this to be correct keeps giving 'file changed as we read it' warning. If Afr instead has to choose to unwind after post-op, eager-lock, delayed-post-op will have to be disabled which will lead to bad performance for all write usecases. Fix: Don't let client cache stat after write. >Change-Id: Ic6062acc6e5cdd97a9c83c56bd529ec83cee8a23 >BUG: 1302948 >Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> >Signed-off-by: Anuradha Talur <atalur@redhat.com> >Reviewed-on: http://review.gluster.org/13785 >Smoke: Gluster Build System <jenkins@build.gluster.com> >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >CentOS-regression: Gluster Build System <jenkins@build.gluster.com> >Reviewed-by: Niels de Vos <ndevos@redhat.com> BUG: 1335285 Change-Id: Ibef4fc80496d12acd15db57713af2e3a1c9109a7 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/14300 Smoke: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Ravishankar N <ravishankar@redhat.com> Reviewed-by: Niels de Vos <ndevos@redhat.com>

* readdir-ahead: Prefetch xattrs needed by md-cachePrashanth Pai2016-05-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Negative cache feature implementation in md-cache requires xattrs returned by posix to be intercepted for every call that can possibly return xattrs. This includes readdirp(). This is crucial to treat missing keys in cache as a case of negative entry (returns ENODATA) md-cache puts names of xattrs that it wants to cache in xdata and passes it down to posix which returns the specified xattrs in the callback. This is done in lookup() and readdirp(). Hence, a xattr that is cached can be invalidated during readdirp_cbk too. This is based on the assumption that readdirp() will always return all xattrs that md-cache is interested in. However, this is not the case when readdirp() call is served from readdir-ahead's cache. readdir-ahead xlator will pre-fetch dentries during opendir_cbk and readdirp. These internal readdirp() calls made by readdir-ahead xlator does not set xdata in it's requests. Hence, no xattrs are fetched and stored in it's internal cache. This causes metadata loss in gluster-swift. md-cache returns ENODATA during getxattr() call even though the xattr for that object exists on the brick. On receiving ENODATA, gluster-swift will create new metadata and do setxattr(). This results in loss of information stored in existing xattr. Fix: During opendir, md-cache will communicate to readdir-ahead asking it to store the names of xattrs it's interested in so that readdir-ahead can fetch those in all subsequent internal readdirp() calls issued by it. This stored names of xattrs is invalidated/updated on the next real readdirp() call issued by application. This readdirp() call will have xdata set correctly by md-cache xlator.

* glusterd: add defence mechanism to avoid brick port clashesPrasanna Kumar Kalever2016-05-101-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intro: Currently glusterd maintain the portmap registry which contains ports that are free to use between 49152 - 65535, this registry is initialized once, and updated accordingly as an then when glusterd sees they are been used. Glusterd first checks for a port within the portmap registry and gets a FREE port marked in it, then checks if that port is currently free using a connect() function then passes it to brick process which have to bind on it. Problem: We see that there is a time gap between glusterd checking the port with connect() and brick process actually binding on it. In this time gap it could be so possible that any process would have occupied this port because of which brick will fail to bind and exit. Case 1: To avoid the gluster client process occupying the port supplied by glusterd : we have separated the client port map range with brick port map range more @ http://review.gluster.org/#/c/13998/ Case 2: (Handled by this patch) To avoid the other foreign process occupying the port supplied by glusterd : To handle above situation this patch implements a mechanism to return EADDRINUSE error code to glusterd, upon which a new port is allocated and try to restart the brick process with the newly allocated port. Note: Incase of glusterd restarts i.e. runner_run_nowait() there is no way to handle Case 2, becuase runner_run_nowait() will not wait to get the return/exit code of the executed command (brick process). Hence as of now in such case, we cannot know with what error the brick has failed to connect. This patch also fix the runner_end() to perform some cleanup w.r.t return values.

* rpc: define client port rangePrasanna Kumar Kalever2016-05-101-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: when bind-insecure is 'off', all the clients bind to secure ports, if incase all the secure ports exhaust the client will no more bind to secure ports and tries gets a random port which is obviously insecure. we have seen the client obtaining a port number in the range 49152-65535 which are actually reserved as part of glusterd's pmap_registry for bricks, hence this will lead to port clashes between client and brick processes. Solution: If we can define different port ranges for clients incase where secure ports exhaust, we can avoid the maximum port clashes with in gluster processes. Still we are prone to have clashes with other non-gluster processes, but the chances being very low, but that's a different story on its own, which will be handled in upcoming patches.
